Heavy Duty Industrial Explosion Proof Metallurgy Blower Fan
Product Features
It is boiler induced draft fan with a total internal pressure
efficiency of 90.5% specially designed to be suitable for various
coal quality and equipped with a smoke-and-dust removal device
(1~20 tons/hour).
This type of fan is currently used in the boiler industry. The air
volume of the induced draft fan and the difference in wind pressure
are relatively large, in order to adapt to the above situation,
considering the practicability of the fan, in addition to the
20-ton boiler ID fan need large power coupling direct transmission,
the other uses the triangular belt type transmission.
This can use different speeds to meet the requirements of various
dust collectors in the same tonnage boiler, combined redundant fan
series and machine number.
It is used to transport various common gases and hard materials in
industrial production, and is suitable for various harsh conditions
such as high temperature, wear and corrosion.

Advantages
1. The fan blade placement angle is optimized, more wear-resistant
and longer service life.
2. The air damper can be used to flexibly adjust the pressure and
flow of the fan during operation. It is also possible to select a
variable frequency motor, with adjust the pressure and flow of the
fan by changing the speed.
3. For the material of impeller and main shaft, we will choose
high-strength carbon steel, low-alloy steel, high-temperature alloy
steel, high temperature resistant high-strength alloy steel under
different working conditions temperature and working speed, so that
the impeller and main shaft still maintains a reliable strength at
high temperature.
4. Fan systems with impeller diameters less than 1400 mm at normal
temperature do not require additional bearing cooling devices,
reducing users’ investment and maintenance.
